How To Stop Html Form From Refreshing

When working with HTML forms, you might have noticed that the page refreshes every time the form is submitted. This can be quite annoying, especially if you are trying to submit data without having the page reload. Fortunately, there is a simple solution to this problem, which we will discuss in this blog post.

Using JavaScript to Prevent Form Refreshing

The key to stopping a form from refreshing the page is to use JavaScript to intercept the form’s default submit action and prevent it from occurring. Here’s how you can do it:

  1. Create your HTML form as you normally would:
<form id="myForm">
  <label for="name">Name:</label>
  <input type="text" id="name" name="name">

  <label for="email">Email:</label>
  <input type="email" id="email" name="email">

  <button type="submit">Submit</button>
</form>
  1. Add an event listener to the form, listening for the submit event:
  2. document.getElementById('myForm').addEventListener('submit', function(event) {
      event.preventDefault();
    
      // Your custom logic here...
    });
    1. Inside the event listener, call the preventDefault() method on the event object. This prevents the default behavior of the form submission, which is to refresh the page.

    With this simple JavaScript code in place, your form will no longer refresh the page when submitted. You can now add your custom logic inside the event listener to handle form data submission using AJAX, for example.

    Example: Submitting Form Data Using AJAX

    If you want to submit the form data to a server without refreshing the page, you can use AJAX. Here is an example of how to do this:

    document.getElementById('myForm').addEventListener('submit', function(event) {
      event.preventDefault();
    
      // Create a new FormData object, passing in the form element
      var formData = new FormData(event.target);
    
      // Create a new XMLHttpRequest object
      var xhr = new XMLHttpRequest();
    
      // Set up the AJAX request
      xhr.open('POST', 'your-server-url', true);
    
      // Set up what to do when the request is completed
      xhr.onload = function() {
        if (xhr.status === 200) {
          alert('Form data submitted successfully');
        } else {
          alert('An error occurred while submitting the form data');
        }
      };
    
      // Send the AJAX request with the form data
      xhr.send(formData);
    });

    With this code, your form data will be submitted to the specified server URL without refreshing the page.
